Multi-User 



UniFLEX is the first full capability multi-user 
operating system available for microprocessors 
Designed (or the 6809 and 68000, it offers its 
users a very friendly computing environment. 
After a user logs-in' with his user name and 
password, any of the system programs may be 
run at will. One user may run the text editor 
whiie another runs BASIC and still another runs 
the C compiler. Each user operates in his own 
system environment, unaware of other user 
activity. The total number of users is only 
restricted by the resources and efficiency of the 
hardware in use 



The design of UniFLEX, with its hierarchical file 
system and device independent I O, allows the 
creation ot a variety of complex support 
programs. There is currently a wide variety of 
software available and under development 
Included in this list is a Text Processing System 
for word processing functions. BASIC interpreter 
and precompiler for general programming and 
educational use, native C and Pascal 
compilers for more advanced programming, 
sort merge for business applications, and a 
variety ofdebug packages. The standard 
sysfem includes a text editor, assembler, and 
about forty utility programs. UniFLEX for 6809 is 
sold with a single CPU license and one years 
maintenance tor $450.00. Additional yearly 
maintenance is available for $100.00 OEM 
licenses are also available, 



FLEX 



Multi-Tasking 



Not only may several users r 
programs, but one user may run several 
programs at a time For example, a 
compilation of one file could be initiated while 
simultaneously making changes to another file 
using the text editor. New tasks are generated 
in the system by the 'fork" operation Tasks may 
be run in the background or 'locked' In main 
memory to assist critical response times. Inter- 
task communication is also supported through 
the 'pipe' mechanism 



UniFLEX is offered for the advanced 
microprocessor systems. FLEX, the industry 
standard tor 6800 and 6809 systems, is offered 
for smaller, single user systems. A full line of FLEX 
support software and OEM licenses are also 
available-

Programme 
ala Pascal. 



Some people say IJAS1C09 is really a 
PASCAL in disguise, others say lis slill 
BASIC. You'll understand Hi is delightful 
dilemma when you look al both versions of 
the "huhhle sort" program shown below: 
both can be run by HASIC09. The program 
on top is unstructured and hard to under- 
stand, hut it's traditional HASIC. The pro- 
gram on the bottom is well-structured and 
easy to follow, a virtue of PASCAL With 
IJASICM you can program cither way. or 
mix the best of both. It's like gelling two 
languages for the price of one.

Makes programs better 

I3ASIC09 has five kinds of loop structures: 
WHILE . . DO. REPEAT . . UNTIL. 



LOOP . . ENDLOOP. FOR . . NEXT and 
IF . .THEN . . ELSE. If one of the five 
built-in data types (byte, integer, real, 
siting, and boolean) doesn't suit the pro- 
blem, you can make a now one of your lik- 
ing with the TYPE statement. Need a tree, 
linked list, or symbol table? Complex non- 
rcclangular data structures using any com- 
bination of data types are easy to define. 
Modular programming breaks down large 
programs to smaller, more manageable 
elements. HASIC09 leLs you create in- 
dependent program modules called "pro 
cedures" with local variables for recursion 
plus parameter passing to any other 
HASICtfe) or machine language procedure. 
There is a complete set of statements for 
device-indc|n:ndcnl settuenlial or random 
l«>. plus a Milxrlative PRINT US1NC. 
system. 
Makes programs faster 

No full-feature HASIC for any H-bit 
microprocessor is faster than liASICHK*. 
because it is an interactive compiler. As 
each program line is enteral, it is instantly 
compiled Ui a smaller, faster form. Hccau.so 
HASIC09 automatically converts programs 
back to original "source" form for listing, it 
is as friendly and easy-to-use its traditional 
interpreter UASICs. Each procedure can be 
independently compiled lo position- 
independent, reentrant, ROMable 
format. Microware' developed a 
new ultra-fast "-digit-accuracy 
floating point math system just 
for HASlCtfy. And if that's slill 



no) fast enough, there's HYTE 
and INTKl'.EH arithmetic. 

Features that make 
programs easier to write 

The compiler is integrated with a full- 
lealurc string AND line-number oriented 
text editor. If you make a mistake. 
HASIC^I lells you instantly. Slrinjt-oricnled 
commands such as search, change, change 
all occurances. delete, and mscil tan he 
used on programs with or ivithoul line 
numhers. There's an automatic line 
renumbering function loo. 

Features that make 
programs easy to test 

Debugging often takes longer than writing 
a program. Thai's why HASKWs integral 
high-level debugger sels it apart from all 
other compiled Ol< interpretive languages. 
The TRACE command shows you each 
statement executed in HASIC form, plus 
the result of any expression evaluation. 
STEP lets you run one or more statements 
al a time. LET and PRINT allow you to ex- 
amine or change the values of variables, by 
name. STATE lists procedure calling order. 
And there are nine other debug com- 
mands. If you need lo correct a program, 
you can edit, recompile, and rerun it in 
seconds. 

Microware* software is available for most 
popular (iMtril computer systems. Source 
listings and yearly maintenance update- 
service are sold separately for most pn>-

Does timesharing 
small system make 




with 
OS-9 
Level One! 

Now two tor more) acts can share your 
microcomputer stage. You will no lunger 
have lo w;dk away from your computer 
while it is busy running a long program. 
Because OS-9 is a multitasking operating 
system, you can he running a ISASIC pro- 
gram while editing a PASCAL program, for 
example. This lets you make more efficient 
use of your lime and your system, even if 
you only use one terminal. If your applica- 
tion requires multiple, independent ter- 
minals, one OS-9 system can do the work 
of several smgle-user systems. 

The convenience 

of an advanced operating 

system 

Sophistication does not require complexity. 
Many OS-9 users say that it is actually 
easier to use than the older n80t)-lyT>e 
operating systems. Consider how easy it is 
to run multiple programs: to run a program 
you just type its name and hit return.* To 
run a program as a separate joh. you type 
its name, an '&' character, then hit return. 
The program runs as usual, but OS-9 
comes back immediately and is ready for 
your next command. Simple commands let 
you see each program's status, set its 
priority, or alxirt it. 

The file management system has fast, 
byte-addrcssahte random-and sequential- 
access tiles. The tree-structured multiple 
directory system lets you create separate 
disk directories for each user, project, or 



application. Command line IN) tile redirec- 
tion means you specify what device and/or 
tiles a program will use when you run it. 
not when you write it. 

Efficiency and 
hardware versatility 

No other operating system can run on such 
a hroad range of hardware: the overall 
HAM requirement for Ixvel One is 32K lo 
5tiK HAM. Memory utilization is superlative 
because OS.9 lets multiple tasks '"share" 
the same reentrant program. For example, 
if two users run BASICW9, only one "copy" 
is actually loaded into memory. The Level 
Two version of OS-9 can utilize up to a 
megabyte of memory on systems having 
memory management hardware 
(holh versions come with com- 
plete timesharing support). 

OS-9's device independent I/O 
system can handle almost any 
number and combination of I/O 



devices: five or eight inch disk- 
ettes, Winchester disks, disk car- 
tridges, serial and parallel ports, 
memory-mapped video 
displays, and more. 
Microware* offers a large selection of 
"stock" device interface softwaie modules, 
or you can create your own: all the infor- 
mation you need is in the manuals. 

Excellent support and 
documentation 

Each OS-9 package comes with a User's 
Manual and a System Programmer's 
Manual that cover every aspect of OS-9. If 
you have special requirements, you can 
even purchase the Source Code for most of 
OS-9 and related software. At 
Microware* we take pride in offering the 
best customer support in the business. 
Technical advice and assistance by phone, 
mail or telex is available during all business 
hours. 

Superb software tools 

In addition to BAS1C«I9, Microware* offers: 
ail Interactive Assembler, Macro Text 
Editor. Stylograph Word Processor. In- 
teractive Debugger, and coming soon. 
COBOL. PASCAL and C language com- 
pilers.

DATABASE MANAGEMENT 

MEANS BUSINESS 



DATAMAN Is made up of 16 menu-driven programs which 
make up a powerful sequential DBM system under FLEX 
You can think ol DATAMAN as a computerized card* Index. 
Use DATAMAN at home to keep track of your household 
possesions, record and tape libraries, mailing lists tor 
cards and letters, elc. for your business, use DATAMAN 
for product Inventory, newsletter subscriptions, marketing 
systems, check balance reconciliation and much more 
The uses are limited onty by your Imagination. DATAMAN 
turns your 6800/6809 computer Into a powerful database 
management system which can save you a great deal of 
lime and money 

You can create databases and do maintenance. Report 
writing is easy with both vertical and horizontal formats. 
Both 80 and 132 column reports are supported In the 
horizontal lormal Formats are saved with run time options 
available. Label printing Is made easy with up to 3 easily 
changed label drivers on line, and as with other DATAMAN 
output programs, the output can be spooled to disk for 
later printing. A statistics package gives up to 24 

statistical values. You can Iransfer records from one 
database to another, blow away records, even merge two 
unlike databases together on a key Sorting on up to 20 
heya is done with a sort editor which uses ihe TSC 
Son/Merge package. You can even build *PR" tiles (or 
use with the TSC Text Processor lor form letters. Invoices, 
reports, etc. The list of features goes on and onl 

You can create a database with any number ol fields 
Most database systems require you to limit Ihe total dale 
In one record to 2S4 characters or one sector Not so 
wtlh DATAMANI DATAMAN allows your records 10 be Ol 

any length. We made DATAMAN to work for you not 

against youl 

DATAMAN was designed for easy modlllcallon and 
customizing with a 'SHELL' program. A 'SYSTEM. GEN" lite 
allows almost any terminal or printer to be used with 
DATAMAN. Comes with every line ol source code, 

program and variable descriptions, and a 160+ page ring 
bound manual that Is second to nonel

RANDOM ACCESS 



If you work with databases containing more than 20 
records and you need super last look-up and editing. 
DATARAND Is lor you. DATARAND converts DATAMAN 
tiles to random Hies wllh up to 9 keys. No need to 
worry about sector blocking or record length. DATARAND 
takes care ol everythlngl You can look up a record by 
key value, key wildcard, or record number. DATARAND 
uses hashed key Hies which means no slow ISAM 
searches. Editing Is quick and easy using the same 
screen layout* as DATAMAN 

The same 'Record Code* concept Is used to make 
operation simple. In lact. except for Ihe speed. It's hard 
to tell that you're not In DATAMAN. You can add 
records to DATARAND lust like In the "Append" section 
of DATAMAN tile maintenance. When you need to use 
DATAMAN. you can copy the desired records to 
DATAMAN You can also transfer records from 

DATARAND which lakes care of llle reorganization. 
DATARAND comes with an Instruction manual and every 
line ol source coat.

Flex User Notes 

BY: RONALD W. ANDERSON 

3540 STRUBRIDCE COURT 
nn ARBOR. Ml 48105 

COMPUTING ON A BUDGET 

A recent leter from J. Preston Brashear 111 
started me thinking about this hobby from the 
standpoint of many of us who don't have unlimited funds 
to spend on It. (t Include myself In that category). 
Preston Indicated that he Is running MlnlFlex, and 
doesn't Intend to switch to FLEX2 only to have It 
become obsolete too* He Indicates that he may go 6809. 
I can certainly sympathize with such feelings, and the 
feeling of being left high and dry with MlnlFlex when the 
suppliers stopped "supporting" It. Preston Indicates 
that he would gladly buy MlnlFlex versions of software If 
It could be bought from the original sources. After all, 
adding new software Is vastly cheaper tlian starting 
over again with FLEX2. He asks If there are people out 
ttiere who have switched, and want to sell their old 
MlnlFlex software (original disks only). Preston has 
decided to organize the MlnlFlex users, and If you have 
written software or articles on MlnlFlex that have 
appeared In '68' or other publications, you will be 
receiving a letter from him that Is sort of a survey. 
Perhaps by the time you read this, you will already have 
received such a letter, and his project will have gotten 
off the ground. I've sent Preston all the original texts 
of my early "Flex User's Notes", which were filled with 
MlnlFlex software Ideas, with permission to "reprint" 
and distribute them to anyone who wants them. 

I frankly don't have many Ideas regarding the 
problem the MlnlFlex users have regarding obtaining 
software. I do have sympathy for their problems. I do, 
however, have some suggestions for those who have 
more time than money. (That probably Includes all of us 
who burn the 2 AM oil In front of our terminals). 
Perhaps you have noticed the ad for Hemenway 
Associates Software Sourcebooks. I've had good 
experience with them. Hemenway's Relocatable Macro 
Assembler for the 6800 Is very good. The sourcebook 
costs S24.95 (RA6800ML). To use the assembler, one 
needs LINK68, the Linking Loader at 17.95. Both use the 
same system dependent driver module. I believe 
Hemenway has a FLEX2 driver available, which he will 
supply If you ask about It. I don't know the price. If 
Hemenway Is not Interested, I have a FLEX2 version (of 
the driver) and can generate a MlnlFlex version rather 
easily. I will supply a listing for reproduction and 
postage costs If Hemenway doesn't supply it. Please 
check with them first. 

The Assembler and Loader can be typed In (If 
you type fast) In about 50 hours, and If you are careful 
to keep 1he line count the same as In the sourcebook, 
you will not have much trouble with debugging It. 
Someone recently asked me If there Is a good cross 
assembler to run on a 6809 system to generate 6800 
code. We decided that one could modify the Hemenway 
code to assemble with the 6809 T SC assembler. Of 
course, the assembler would still accept only 6800 
mnemonics and would generate 6800 object code. I 
managed the conversion In a couple of evenings, having 
had the source on a disk, and It runs very well. 
Hemenway also has XA6809, a cross assembler Intended 
to run on a 6800 to generate 6809 code. It costs 124.95 
too. It Is possible to assemble this source on a 6809 
(after a few necessary modifications for compatibility) 
and have a 6809 relocatable Macro Assembler with very 
nice capabilities. The same system dependent driver 
package as runs the 6800 assembler and loader, will 
assemble In 6809 assembler and run with this package. 
When you have It working, you can go back and have great 
fun converting the code to take advantage of the 6809's 
extra capabl lltles such as the MUL Instruction. 



If you want a rarlier large project, purchase 
STRUBAL+ In sourcebook form for $49.95. This one will 
probably take over 100 hours to type In. The whole 
package. Including the compiler and various sections of 
the runtime package adds up to well over 13,000 llnesl If 
you have followed this column, you are aware that I have 
It running on my 6800 FLEX2 system. I've been critical 
of this compiler In the past, because It Is not terribly 
memory efficient, but at $50 It beats not having a $250 
to $300 version of Pascal because of budget problems. 
It does (as I have always maintained) work very well. It 
Is not hard to use. Hemenway, Just to mention all of the 
sourcebooks, also has a CPM like operating system 
called CP/68 available In source form for $34.95. All of 
1he above sourcebooks list drivers for CP/68. 

MlnlFlex users, take note that Lucldata 
release 2.1 Pascal Is available In MlnlFLex version for 
$90. This is a version with REAL variables of 9 digit 
precision. It doesn't have scientific functions. You may 
remember that I published a set of functions for those 
several months ago. My functions are not the ultimate In 
either accuracy or speed, but they do work, and give 
results satisfactory for engineering programs, and 
hobby applications. 

FORTH AGAIN 

Frank Hogg's XF0RTH Is now being distributed. 
I've received a copy of the disk and the manual. The 
manual Is something elsel It Is aver 400 pages! This Is 
(as I told Frank) the most comprehensive and 
understandable manual on FORTH that Is available to my 
knowledge. I have "Using Forth" (advertized by Fig as 
1he best manual available). When they see this one, they 
will have to change their recommendation. Believe me, 
Frank's, written by Chuck Eaker Is far more complete 
and comprehensible. Chuck has a facility for explaining 
things In the right order. That Is, he builds on what he 
has already told you. The first part of the manual Is a 
tutorial on standard Fig FORTH. There Is a glossary, 
and of course a section on XFORTH's features too. 
Check 1he ads In this Issue of '68' for the price of the 
manual. I strongly recommend that anyone Interested In 
any version of FORTH get his hands on Ihls manual. Now I 
even understand what the word pair <BUILDS 00ES> does. 
Try reading the Fig glossary description of <BUILDS 
nine or ten times and see If you understand ft. Once 
you understand FORTH, the Fig glossary Is an excellent 
reference, but It Is too concise and uses too may terms 
you must understand before you can understand It, to 
be of much use to a beginner. The XF0RTH manual takes 
a few pages to describe what these words do, and give 
an example or two of their use. I have had a chance to 
get XF0RTH up and give It a workout. See below for 
some results In the way of further timing comparisons. 

ON TO NEW WORLDS 

Well, I've done It. I've decided to write a book 
teaching how to program In Pascal, using BASIC as a 
starting point. I have a feeling that many hobbyists have 
been scared off by the highly technical description of 
Pascal In the Jensen and Wlrth Standard. We who suffer 
from the lack of a couple years of Computer Science 
courses have to have something at a less formal and 
technical level to Illuminate us. I think I am relatively 
simple minded, and I have to break complex things down 
Into terms I can understand. I'm hoping that my 
explanations will be clear to anyone understanding 
BASIC, and that they will help get many more of you Into 
the world of Pascal. The project will take several 
months of my spare spare time. 

PRINT ROUTINE USING A BUFFER 

Several monlhs ago, I noticed the pleas of John 
Tucker for a print routine that uses a buffer, so that 
the disk drives don't have to access so frequently. My 
working attempts are presented here. These versions 



10 



68 Micro Journal 



are for a serial printer on port of a SWTP system and 
a parallel printer on port 7. Notice that the old Inertia 
still has me using P.CMD and PRINT. SYS. This program 
presented an Interesting problem. A print routine can't 
possibly know that you have finished printing, and 
therefore doesn't know enough to empty the buffer If It 
hasn't ended up full, which Is highly unlikely. My program 
overwrites the FLEX WARMS Jump with the address of a 
section of the program that empties the buffer and 
restores the WARMS Jump In FLEX, and then uses It to 
exit back to FLEX. 

Of course the buffer may be moved, expanded, 
or contracted to suit your system requirements. I 
assembled a large program with output to the printer 
using the PBUFF listed here, and the disks were 
accessed about every 1 2 or 13 pages of textl You may 
need to customize these with your printer drivers but 
conversion shouldn't be too hard, as I've tried to 
distinguish the added parts from the original printer 
drivers. Notice 1hat the part of the print routine that 
doesn't fit In the allotted print driver area Is at the 
beginning of the buffer area. The buffer starts 
Immediately after the end of the driver. 

CORDIC FUNCTIONS 

Since my escapade with the Trig, function 
approximations, one writer has been kind enough to 
send me some Information on CORDIC technique. This 
method may be used to generate the Trig, functions 
accurately and with relative speed. The method consists 
essentially of summing a series of terms, each 
successively smaller than the proceeding one. In such a 
way ttiat the terms add up to the Input angle. Meanwhile, 
based on whether a particular term Is added to or 
subtracted from the sum, an X and Y value are 
manipulated. If one starts with X=l, Y=0 and an angle of 
0, and then sums terms In such a way as to approximate 
the angle very closely, the X and Y terms when divided 
by a constant tliat Is dependent only on the number of 
terms used, become the values of ttie Cosine and Sine 
of the angle respectively. 

I did a program In BASIC to try these out, and 
with 21 terms, was able to get Sine and Cosine 
approximated to 6 full places. The beauty of this 
method Is that the manipulations of the X and Y sums may 
be done by simple shift and add operations. If one were 
using a 6800, this method would be the fastest way to 
arrive at Sine and Cosine. However, the 6809 has Its 
fast MUL Instruction, and the functions may be 
calculated to the same accuracy faster using a 
truncated or "telescoped" series approximation. I was 
also able to use the technique to implement an ARCTAN 
function. The technique may be used for other 
functions ttian these as well. 

MORE TIME TRIALS 

I've had a chance to try out a few more 
compilers on the PRIME number test program. This time 
I've had to extend the Job to finding primes to a limit 
of JO0O0 In order to get the times to be long enough 
for reasonably accurate timing. The program Is not the 
ultlmarely efficient one for each compiler. I've found 
that a technique that speeds up execution In one 
compiler may slow It down In another. The fair test 
seems to be an algorithm that hasn't gotten unduely 
complex in order to save a few percent In execution 
time. Times In seconds are:

TSC Pascal 59 

OmegaSoft Pascal 6' 
Lucldara Pascal 157 
Dynasoft Pascal 142 

♦ miJTU nc 



The FORTH versions use a little trick (only 
possible In FORTH). Since the numbers Involved In 
finding primes are all positive Ingeters, It Is possible 
to take advantage of FORTH's unsigned arithmetic 
functions. Since these are defined for double 
precision, a little manipulation Is Involved, but they are 
still much faster than the single precision signed 
arithmetic. I defined a "FAST MOD" and a "FAST 
MULTIPLY" as follows: 

: F* u* DROP ; 

: FMOD >R R> U/ DROP ; 



The multiply simply uses the unsigned multiply 
U* and drops the high order word of the double 
precision result. FMOD supplies a high order word of 
value zero for 11/ and drops the high order word of the 
result. Ray Talbot Is responsible for the FMOD Idea 
which significantly speeds up the prime program 
presented in the Morelra Article (Feb. '68' Micro 
Journal). Since my algorithm uses a number of multiplies, 
I decided to try an unsigned multiply too, with good 
results. 

DYNASOFT PASCAL 

A number of you have probably used Dynasoft 
Pascal In the cassette version. Al Jost, author of 
Oynasoft Pascal, has recently prepared a 6809 FLEX9 
version. It has much of Pascal Implemented, though It Is 
a smaller Implementation than the several others 
available. The entire runtime Interpreter Is 1173 
bytesl This Is a P-code Implementation. Not 
Implemented are REAL variables RECORD data types, and 
SETS. Surprisingly, the dynamic variable features are 
Implemented with the procedures NEW, MARK, and 
RELEASE. Compile time for the Prime test program, 
results of which ore reported above, was 38 seconds. 
The execution time was quite respectable. 

1 see two very definite markets for this 
compiler. If you want a small Implementation for 
"control" purposes, this would be an excellent choice. If 
you are a beginner and want to try out a Pascal before 
spending a larger amount on a full Implementation, or If 
you don't need REAL variables Implemented, this Is also 
a good choice. Cost for the compiler without the source 
listing of the runtime Interpreter Is $60. With the 
runtime listing, the price Is $90. The listing will be 
included on the dlsketre and will convey a license to use 
the Interpreter In target systems (le. processors to 
be sold as part of a control package for a machine 
etc.). Al has Indicated that he presently has no plans 
for a 6800 version, but "I could probably be pressured 
Into doing It If there were enough demand." This 
software will be available from Frank Hogg Laboratory 
(probably In his ad In this Issue).

DUMP 



by Jeff Brown 



A Memory dump is one of the most useful 
computer utilities. Unfortunately, Good 
memory dumps are scarce for many micro 
systems. On my SWTPc 6800 system the 
only way I could get a memory dump was 
by doing a cassette dump (SWTBOG command 
"P"), and trying to separate the memory 
contents from the header and checksum. 
This is very tedious when you are faced 
with a continuous stream of letters and 
numbers. In addition to that 
inconvenience, no ASCII was printed to 
help interpret the numbers, and the 
output could not be printed on a line 
printer. 

This program is virtually monitor 
independent (except for the input 
routines). All the output routines are 
contained in the program so a line 
printer, or any other device, may be 
used. The only modification required to 
run on another 6800 system is to adapt 
the printer initialization and driver 
routines for your printer. If you won't 
be using a printer, the init and driver 
can be replaced by N0P°s. DUMP occupies 
the high end of memory, and uses no 
"page 0" storage so the program should 
not interfere with anything else. It 
can be relocated by changing all the 



S6XXX references to 1,2,3,4,5, or 7 to 
locate it in high memory. 

Using The Program 

When run, DUMP will identify itself, 
and proceed to ask for a line interval. 
This is actually the line length of the 
output. This would normally be $10, by 
convention, but any value will work. 
This is very useful if you want to 
examine a fixed format table in memory, 
or use the whole width of a wide sheet 
of computer paper. In any event, the 
input routine requires a 2 hexadecimal 
value to be entered. Then the starting 
address is requested, followed by the 
ending address. These must be A digit 
hexadecimal values. Then DUMP asks for 
the output device. The response should 
be either a "C" for the console, or a 
(CR) (carriage return) for the printer. 
The printer is effectively the 
"default". This can be changed if 
desired. DUMP will then output the 
contents of the specified memory block. 

This is the most useful memory dump I 
have seen for the 6800. Having a 
variable line length has been a valuable 
feature for me - I hope that you will 
find it as useful.

Why. a linking leader? 

If you have never attempted to write a 
major assembly language project, you might 
not understand the reason for all the fuss 
and bother. However, I think anyone who has 
tried to write a 300 line absolute assembly 
program will appreciate RLOAD. 

The thing you get from a linking loader 
Is the ability to write modular code In an 
easy-to-use format. nodularity can be 

16 



achieved by use of the LIB feature of TSC's 
assembler, but In order to use that, you must 
re-assemble all of the code In the entire 
program to change any part of it. Also, if 
your collection of general-purpose sub- 
routines begins to grow large, you begin 
having problems with keeping symbols unique. 

A linking loader, on the other hand, 
allows you to make a change in a program by 
assembling a single subroutine, and having 
the loader Install it into the program. It 
is similar to appending several subroutines 
together, except that you don't need to worry 
about where each routine is going to be 
loaded, and you can 'append' several routines 
at once. The loader takes care of all the 
bookkeeping, and even furnishes a map of 
where all the routines are. 

With a linking loader, it becomes easier 
to build a library of tools such as the ones 
described in SfiltHSrS Iflflls, by Kernlghan and 
Plauger, which can be linked together in 
order to form large, powerful programs very 
quickly. You can also more easily write test 
routines which can exercise a single 
subroutine before linking it into a larger 
program. 

I didn't really start off to write a 
linking loader. What I really wanted was a 
really good Interactive editor. After 
several careful readings of SfiftHarg IfioJs, I 
decided that I could write the editor that 
they described entirely in 6809 assembly 
without a great deal of trouble. 

Things got off to a good start, in spite 
of the fact that all I had to work with was 
an absolute assembler. However, it soon be- 
came clear that some sort of segmentation of 
subroutines would be absolutely necessary. I 
worked out a scheme whereby I could more or 
less relocate a module using a 'counter' 
scheme, but I still had to re-assemble all of 
the subroutines in a program to run it. I 
worked out another scheme with which I got a 
little farther, but it was obvious something 
entirely different was required when . I ran 
out of symbol table space... 

Then I had a disk failure, which wiped 
out nearly all of the work I had done on the 
editor. (I am currently in the habit of 
keeping no fewer than two backups...) 

As I was sinking slowly into the deep 
gloom of hopeless depression, inspiration 
struck. It appeared possible to fool the 
assembler into generating records which could 
be used to relocate and link subroutines. By 
using ORG statements addressing memory that 
doesn't exist on my system, I could generate 
different types of records which could be 
used by a special loader. 

I quickly composed the macros for ENT and 
EXT, at which time I saw that the design 
could be simplified by the macro MODULE. My 
friend, Paul Schumann, agreed to 'walk 
through' the code with me. He suggested that 
I include some other features in the MODULE 
macro. He also suggested that RLOAD should 
build a core-image file, Instead of using a 
load-and-go arrangement. This would allow 
the linking of programs larger than the 
memory capacity required to run RLOAD. 

Although Paul is an accomplished software 
guru, he was not familiar with the 6809. 
Then. When he found out the beast has TWO 
stack pointers, he rushed out and got his own 
manuals on it. I think he is now 'hooked'. 

I had originally hoped that I could use 
the loader to bootstrap itself directly, but 

18 . 



as the design evolved, I found that I would 
have to go back and modify the source for 
each module instead of Just changing the 
macros and re-assembling. Fortunately, the 
required changes were minor. 

I never did completely finish this 
program, at least at the time I sent this 
article in. Once I got the bare essentials 
running (I got the loader to load itself), I 
Immediately set off using it to write other 
utility programs. The planned additions of a 
sorted symbol table, counters, and user 
directed mapping, although simple enough to 
do, just didn't seem as important once I 
overcame the single worst aspect of the TSC 
assembler. 

The follow 
project : 



ing is an overview of the 



lOBUtS- 

1) File containing all filenames to be 
linked. 

2) One or more binary files containing link 
information. 

Qviauia- 

1) Load map 

2) Symbol table 

3) Core image file 

RLOAD uses a two-pass algorithm. Pass one 
builds the symbol table in core and writes 
the load map to the printer. It spots 
multiple definitions of entry points. 

Interpass outputs the symbol table to the 
printer. Someday, I intend to Install a sort 
routine, (which may happen before this 
version is published) as well as some other 
features designed to make the program easy to 
use. (I am open to suggestions) Undefined 
externals are assigned a value of $FFFF, but 
the current version of the loader does not 
give you any other warning.

The module will not actually be relocated 
In the usual sense of the word, but simply 
moved to another spot In core. Therefore, 
you must use position-Independent code 
throughout. (Exception: Be sure that calls 
to fixed routines such as FLEX calls are NOT 
position-Independent, since FLEX will stay 
put) I chose to use ABS entry points In a 
module named OSLINK for linkage to FLEX. 
That way, If I decide to write a different 
version of a FLEX routine, I can change only 
OSLINK and re-load the program to Install the 
new subroutine, Instead of changing the 
Insert file and re-assembllng all of the many 
subroutines In my system. A close 
examination of the loader Itself will show 
some of the techniques Involved. 

To Invoke RLOAD, enter 



♦++RL0AD, <llnkf llename> 

where <llnkf llename> Is the file containing 
the names of modules to be linked. The 
default extension for <1 lnkf 1 lename> Is .TXT, 
and the defaults for the files to be linked 
Is .BIN. The plus signs are the FLEX prompt. 

Jbsaci st sBsratloc : 

TSC's manual on FLEX Includes an advanced 
programmer's guide which has all the 
necessary Information on the file structures 
and the use of the file manager system (In 
short, all of the Information needed to write 
a program like RLOAD). 

Basically, a logical (not actual) binary 
record looks like this: 

Byte Contents 

Start of record Indicator ($02) 

1-2 Load address 

3 Byte count (of data) 

H-n Data 

The transfer address record Is a three-byte 
record beginning with $16, and containing the 
entry point address. 

The physical record may have more than 
one logical record, and a logical record may 
span physical records. 
'68' Micro Journal 



For more detailed Information, you should 
consult the section on the file management 
system (FMS). 

RLOAD reads the logical binary records, 
and identifies the records with addresses 
$FFF0-$FFF3 as special. The listing of the 
main routine Includes the expansion of the 
Insert files (using the LIB feature). These 
special markers are generated by the macros 
ABS, ENT, EXT, and MODULE. ABS is used to 
Indicate an absolute entry point, i.e. a 
pointer to an operating system routine. ENT 
is used to indicate a relocatable entry 
point. EXT is used to allocate a link word 
for the module to used for access to the ABS 
and ENT entry points in other modules. The 
MODULE macro is for the purpose of measuring 
the length of the module (along with ENDMOD), 
and for inserting an arbitrary string into 
the load map. I realize that there are other 
ways of accomplishing the length measurement, 
but I chose the easy way. 

A word of caution: If you make a mistake 
and write any code which is not position- 
independent, the resulting problem can be 
very difficult to find. Generally, the 
symptoms are: You have just assembled a 
subroutine, and load it into memory by Itself 
to test it using a debugger. It works Just 
fine, so you link it into a program which 
will use it, and the program immediately 
wanders off into the weeds. Explanation? 
The first position-dependent Instruction 
encountered just sent the processor somewhere 
into low core. 

There are many things which could be 
added to RLOAD. In addition to adding the 
SORT routine, and implementing counters, as I 
had originally planned, it would be almost 
trivial to add a COMMON feature. One thing I 
did add just before this release was the ABS 
statement, which works like an ENT statement, 
but does not cause the entry to be relocated. 
In the module OSLINK, I used this feature to 
load the symbol table with the FLEX addresses 
used in the loader. 

You may have noticed that there is a 
small problem in Just assembling the source 
as presented in the listings. You will end 
up with all of the linkable binaries, and no 
way to link them. The way I got around this 
bootstrap problem was to prepare a special 
set of macros for the EXT links, and set the 
origin of each module, and inserted these 
values in the EXT statements of each module. 

Example: In the Insert file MODULE. MAC, 
use 



EXT MACRO 

ORG EXTORG 

FCC 'il'.EOS 

CTR 
41 FDB 42 Compare to listing 

ENDCTR 

ENDM 

And in a program which uses (arbitrary example) 
WRBNRC: 

EXT WRBNRC, $0E50 (From load map) 

In WRBNRC, you will need to add: 

CTRO SET JOEttC

Thie article deecribea how to interface a Heetftkit 
Xicroproceeaor Trainer ET-3400 and a Heethkit Meaory 
and Input/Output Accessory ETA-3400 (TM Heath Co.) 
to a SS-SO buss. It provides the ET/ETA-3400 owner 
with suggestions on hardware and software requirements 
necessary to expand the units into a more usefull and 
flexable system. 



Information about the author 



Presently Manager of his own Insurance/indent Sales 
business, 36 ye*rs old, graduate of the "College of 
Hard Knocks" (Ex-US Coast Guard Electronics Technician) 
the author entered the Electronics Pield at the tender 
age of 13 when he wanted to know why the crystal radio 
he'd borrowed from his cousin didn't need batteries. 

Wbile In High School, he took a two year correspondence 
course in Basic Electricity. Elementary Electronics and 
TV and Radio Repair from De Vry Technical School. After 
High School, he entered the US Coast Guard, attended 
Electronics Technicians School at Grotton, Connecticut, 
and served for an additional three years before being 
discharged as Electronic Technician Second class. Jfe 
t-leo worked for & time with ITT out of their Paramus, 
New Jersey Office ae a Pield Engineer, installing elec- 
tronic equipment under contract with the US Navy. Most 
recently/however/ he has been out of the electronics 
business except in the conputer hobby area. 

Almost everyone who has the ET/ETA-3400 MUST hrve, at one 
time or another thouqht about expanding it into a bigger 
more ueefull system. The following article will describe 
how 1 interfaced ray units to a SS-50 Buss.

easy way to start* anc* you Tain . 5K of RW to be used for 
scratchpad and stack. My thanks to Jart«*s Creoer for his 
help with this and the RE line moJif icatior, 

Thoae of you who have both the trairer srd the add-on 
know that when you purchase the add-on. Heath tells you 
to pull XCs 14-17, and not to reinsert then* when you are 
using the ETA-3400 as this would mear thet the trainer is 
addressing two BAMs in the 0000-0 Iff (Hex) area. To change 
the RAM addressing, cut the trace thet connects IC3 pin 13 
and IC2 pin 1, then run a Jumper froc IC3 pin 13 to one of 
the IC2 pins as shown in Fin. 1. I used A00O-AlPF<Hex) as 
this ia the address that Southwest uses. You should note 
that if you ever would like to rur the trainer by itself, 
you'll hove to renove this nod or install a SPTT switch 
ao you can readdress these RA*i brck to OOOO-OIPF(ICex) . 

BY THE WAY, if you don't know how to tell pin 1 of an 1C 
froir s capacitor, you SHOULD NOT TRY THPSE MOflipicATlONS 
or at Le/at, have assistance from eoireone who doesl 

THE ET-3400 ftF LINE 

There seems to be a lot of misunderstanding about use of 
the re Line. This line controls a set of two-directional 
buffers which allow the CPU to either reed fron RAM or an- 
other address or, by changing the direction of the buffer 
to write to RAM or another address, when the R£ line is 
low, the buffers are in the read direction, and when the 
AE line is high, the buffers are in the write direction. 

The RE line is required by the ETA-34on artri-on, and the 
lire is brought out so the ETA-3400 can control the line 
and turn the buffers in the direction the ETA-3400 needs 

18 __ 



for propor operation. The problem here ia if you try to 
add additional memory cards and you tie into the RF line 
at the Trainer's 40 pin connector, you have two or more 
RA^'s all trying to fight for control of the *F line. If 
however, we move the diode to each menory cart, then each 
card will be able to use the RR line correctly. 

This 1b also eesy to modify. Remove the Diode And the wire 
that Heathkit has you Install in the trairer, and replace 
it with a wire between the eame pins. This iP from the RE 
connector to pins 6 & 3 5 on the 40 pin connector. Second, 
open up the ETA-3400 and cut the trace runnino r rom the 
IC 107 pin 1 to pins € fc 35 on the 40 oin connector. Then 
install the diode you relieved from the trainer over the 
cut on the trace. It should be installed with the banded 
and tward IC 107. While you have the ETA-3400 open, cut 
the trace between pins 15 k 26 of the 40 oin connector. 
This last cut will free pin 26 for the next step. 

VMA LINE REROUTING 
In the ET/ETA-3400 ayetew, the VMA line la ANDed with the 
02 line by IC 5 and run to the ETA-3400 os the VKA.02. 
The SS-50 buss requires a seperate VHA Line. To do thla, 
cut the trace in the trainer between pin* 15 & 26 on the 
40 pin connector. This leaves the 02 line on pin 15. Last, 
run a wire fron pin 26 on the 40 oin connector to the vya 
output connector on the underside o f the trairer. 

That completes the noda to the trainer and add-on. Mow 
our 40 , pin connectors hrve pinouts as shown in Pig 3. The 
original pinouts are shown in Pig. 2. 

SYSTEM CHECKOUT 

Well, if you've stuck with it this far, you'll want to be 
sure that you didn't harm anything in any of the steos so 
far. Locate those 2112's that were supplied with the ET- 
3400 and the course, and insert then in the IC sockets on 
the face of the trainer. Next, reconnect the 40 pin ribbon 
cable between the ET-3400 £nd the ETA-3400. then close 
everything up after a final inspection for loose wires, or 
any other problems. Power-up the system, and use your ET- 
3400 meaory exam/chance keys or the terminal and look at 
addresses AOOO-AlFP(Hex) . If you've done everything OK, 
you should see good memory at these locations. 

If you have a set of memory testa, run the tests on the 
addresses A000-A1PP (Hex) . If you have not yet purchased a 
set of rrenory tests, use your SLIDE control and SLIDE out 
of ROM the memory test at 1 A34-1A6K (Hex) in the ETA-3400. 
I'd suggest you relocate it starting at 0134, by punching 
in SLIDF 1A34,0134,PP <CR) . Next, use your memory exam and 
chanve the following; 



New Address 

0181 

0169 

016B 



Pcom To 

CE 1000 CE 0100 

CE 00DP CE A1PP 

ac ffpf ec aooo 



Before starting the aeraory tests, uee your memory exan/ 
chan9e and set all of the AOOO-AlFP(Hex) ad r esses to 
00. Lastly, jump to the memory test which now starts at 
0i34(lte::) by typing in C 0134 (CR) . The altered meaory 
teat program will now check your now memory. 

WIREWRAPP CARD CONSTRUCTION 

Cut a piece of perf-board tc 5" X 9" (BWTPCO standard for 
SS-50 buss cards) and use 5 minute Bpoxy to mount 5 each 
of the 10 pin rtolex female connectors on one aide (the 9 
inch side) of the card. Purchase or fabricate two 40 pin 
connectors with the same pin spacing a as the ones you see 
on the trainer /arti-on . I used two 40 pin wirewrapp IC 
sockets to make r connector by carefully cutting each of 
the sockets tlown the middle* aid then gluing what was the 
outside of the sockets together. Mount the connectors on 
the top edge of the board with Epoxy, and finally, mount 
a 14 pin IC socket in the middle of the board. 

Once the epoxy is hard, you should use a fine felt-tiped 
pen, and label one of the 40 pin connectors as "Trainer" 
and the other as Tdd-on", Then transfer to the card all 
of the pin numbers ard uses shown in F19ure 4 and list 1. 

Lastly, the big job. &nd that is to wirewrapp up the board 
following the connections listed in Figure 4. I'd suggest 
you use ore color of wire for data lines, another for the 
addreas lines, end eo on. This riakes it much easier later 
if ycu have to correct any mlatakes. 

CHECKOUT (AGAim 

Once you are aure you have the wircwrspp board wired up 
correctly, insert a 7404 in the IC socket on the board. 
Now disconnect the 40 pin cable connecting the trainer 
to the adu-on. Connect one erd of the 40 pin cable to the 
connector on the board marked "Trainer", and the other to 
the trainer Itself. Connect a second 40 pin cable to the 
connector on the board narked "Add-on* and the free end 
of this cable to the add-on itself. Then TRIPPLE CHECK 
that you have the cable plugs correct, that is oin 1 on 
the trainer should connect to VMA, 07 on the card, ect. 
It's easy to get these cables ISO out as there isn't any 
index pin to prevent you fron plugging it cither way J I 

'$8' Micro Journal 



Finally, power up the system without TUf CARD CONNECTED 
TO THE SS-50 BUSS. You should find that the trainer and 
the i'dd-on will operate as before you started with the 
exception of the fact that you will now hrve the addition 
of the Trainer RAIfs et AC00-A1PPlHex) . If the units don't 
operate, you havn a wiring error on the wirevrapp card. 
Do rot qo any further untill you correct any problems I 

GETTING THE SS-SO BC'SS GOI*'0 

I used Thctnee Instrumentation menory cards, which are the 
eana pinouts ss the Southwest System as shown on List 1 , 
but before connecting the ET/ETA-3400 to your SS-SO buss, 
it'd be a good ides tc go back snd recheck your pinouts 
ami signal requirements oganat those listed. My system 
only required the inverting cf the VJtA line and the 02, 
but yours nay be different, snd in that case, there are 
several unuaoc" inverters on the 7404 for your use. 

SS-59 BUSS lutes 

Listing 1 cives you a brief description of the pinouts, 
names and def irltior.s of the SS-50 buss used by Southwest 
and tioet companies usitg the 5S-50 buss. Onc> you have re- 
chocko£ your menory cerd requirements sgsnst it, you can 
plug your wirewmpp card into the SS-50 buss. Knke sure to 
plug the tNDHX pin to orevert insertion of the card into 
the buss ircorrectly. 

With your wircwrapp card plugged into the SS-50 bues , but 
without Any other cards plugged into the bues, cower-up 
the ET/ETA-3400 enu check to be sure it operates normally. 
IF NOT, check the SS-SO buse and correct the nroblen. 

Once you peas this test, set your troftery car* addressing 
switches or lumpers to any addrees between 2400 and 8000 
(Hex), and plug the nenorv card into the buss. Before you 
do so, check to make sure there is a oluo in the correct 
hole of the ccrd ncrked iMjex. Power-up the SS-50 buss, 
but not the ET/ETA-3400 and chec/-. the voltage acrose the 
♦ 12V, -12V, and *8V lines to GWT>, These voltaa*a can vary 
by -+20% ana still be acceptable. Next, check the voltages 
on your rrjnory carila. These should be +-S% for the card to 
work correctly. If you find ?ny high or low voltages, be 
eure to correct then before going to the ne::t step. If you 
have a friend who hrs a SS-jO buss conputer, the ideal set 
up would be for you to ssk hie help, and if possible have 
hir- teet your ir-cnory beard in his conputer. 

THE RE LINE (AGAIN) 

Almost done* Coneult the data that care with your memory 
card, and locate the data buffers on the schematic, on 
most cards there will be two buffers, one for D0-D3, and 
ene for D4-D7 just like the ET-3400, If your buffers have 
two enable lines, one low to resd snd another to write, 
you* re in luck. Simply connect a diode aimuler to the one 
now relocated in the ETA-3400 (a GD51Q) to the oin that 
goes low for s read. The bended end should be nesreet the 
IC. Connect the other ord of the diode to UD2 pin which 
connects to the RE Line, if your ncvory cards use one 
line like the ET-3400, that is high to write end low to 
read, you ray have to invert the signal ueing one of the 
apare T404e on the wirevrapp card. 

If all else fails, do as I did, and connect the diode to 
firat one. pin and then the other on the memory card buffer 
untill you find the one that works! On the Thonaa 24K RAM 
card, the correct pin ia IC 105 pin 8. 

IT'S UP II 

Once you have the csrd operating, run menory teats, and/or 
use the program in the firet of this article. You'll have 
to chenge the addreae to natch those on your csrd. 

SOFTWARE 

As it cones from Heethkit, the ETA-3400 is set to use 
0000- 23PF (Bex) . Any memory you sdd will neve to be 
higher then this. This is not too Uniting untill you 
start getting more than 4-8R of menory. Moet of the good 
programs written for this much memory sssume you have free 
and usable menory from 0000 and up. 

If you would like to free the menory from 0000-0800 (Bex) , 
you will have to eerously consider rewriting the ETA-3400 
monitor ROM, snd then burn it into EPROM which can be set 
to EOOOLHex) snd up. To work on the program use the SLIDE 
snd move the Monitor program to RAN. It will be then up 
to you to change all of the 3 BYTE inatructiona to the new 
address of your EPROM. Host of the data that needs to be 
changed ia easy to spot, just use your "I" convnand, and go 
thru the program. One "hidden" piece of data that ia not s 
3 BYTE instruction ie at 1462 (Ilex) C6 14. This is the MSB 
of the return address, and should be changed to the MSB of 
your EPROM's sddrese. The addreae tsble must slso be 
rewritten to the new address. Lastly, you'll have to work 
to readdrees the PIA, which is now at 1000(Bex), 

One word of caution, even after you reburn your monitor to 
EPRD:i, and locate it above the free memory, the ETA- 3 4 00a 
monitor makes hesvy use of the 00 page, 0000-00FP(Hex) snd 
this will require rewriting some of the commercially avai- 
lable programs because of addressing conflicts.

Mailing Package 

This software enables the computer operator 
to send out business letters and envelopes such as 
would accompany a resume for a Job search In a more 
personal manner. There are seven programs which 
Include C0VLET, ENVELOPE, SEARCVLT, SEARENVL, 
SREXAMZP, SRCVLTZP, and SRENVLZP. These programs 
operate on a file called DATC0MP which contains the 
pertinent Information: 



1} the name of the company 

2) 1he name of ttie Individual to be contacted 

3) the above person's title 

4) the .department 

5) the street address 

6) the city, state and zip code. 



The computer operator is assumed to have 
prepared the master copy of the letter he/she Intends 
to mall out and to have made photo lithographed copies 
which only require the addition of the date, heading, and 
greeting. Size 10 envelopes are to be used and may or 
may not have the computer operator's name and address 
in ttie upper left hand corner. 

COvLET prints to the companies contained In 
0ATC0MP a letter for all companies one company after 
another. ENVELOPE prints to the companies contained In 
DATC0MP an envelope for all companies one company 
after another. SEARCVLT permits a search for a 
particular company and then It is possible to print the 
date, heading, and greeting to that company and to the 
companies which follow the sought for company. This Is 
useful If the entire contents of DATC0MP were not 
printed at one sitting and one wishes to print the 
remainder of ttie letters to the companies. SEARENVL 
permits a search for a particular company and then It Is 
possible to print the name and address to that company 
and to the companies that follow the sought for 
company. This Is useful If the entire contents or 
DATC0MP were not printed at one sitting and one wishes 
to print the remainder of the envelopes to the 
companies. SEARCVLT and SEARENVL also permit one to 
locate 1he line numbers In ttie BASIC program DATC0MP 
where the particular company resides in order ttiat the 
DATC0MP file maybe changed and updated. 

SREXAMZP allows the computer operator to 
examine DATC0MP by zip code In as general a manner as 
the first leading digit or as specific a manner as a full 
five digits. Hardcopy of the sought for companies may 
be produced. SRCVLTZP allows one to print letters to 
companies by means of a search similar to that 
conducted for SREXAMZP. SRENVLZP allows one to print 
envelopes to companies by means of a search similar to 
that conducted for SREXAMZP. 

To use the mailing package, one loads the 
master program and then appends the DATC0MP file to 
It. DATC0MP files start at line 1100 and follow ttie 
format shown In the example. 

It is estimated that letters and envelopes can 
be produced at a rate of 500 per twelve hour p erlod.

THE Speaker 



hardware and use of vast amounts of memory make it 
somewhat less desirable 1han -the system used by this 
board. The second method Is a variation of the above 
allowing an unlimited vocabulary, by storing the 
elements of spoken words (phonemes), and then having 
the output device (normally a computer) reconstruct 
them Into vocal words, phrases and sentences. This Is 
an Improvement over the above but still uses far too 
much storage (memory) space. The third method (used by 
the Alford VS- 1 Speaker) Is an Improvement of ttie 
second. Esssentlally what is done is this; a model of the 
human vocal tract Is emulated by hardware and software 
to produce speech. This review cannot provide the 
space to go into a detailed paper on this method, 
suffice to say that the giant steps In Integrated circuit 
design has made such efforts possible and available 
now, to the average computer user. Basically it involves 
a combination of an electronic model of the human vocal 
tract, control code ROM and latches and logic In a 
single IC (SC-01) to Implement a device to generate a 
single phoneme for each byte sent by the computer. 

An example of the following sounds and the code 
to produce them illustrates the simplicity of speech 
generation: 

The word 'FATHER' would be coded as follows: 

If by using this system we coded the word FATHER we 
could write the sound of 'a' as 'AH1'. The I Indicates 
the duration of the sound, the AH the type of sound we 
desire, such as the broad 'a' as In FATHER, By using the 
supplied charts the word would be constructed as 
follows: 

F AH1 THV ER 

Also we might want to Include speech inflection 
or pitch. The inflection or pitch symbol used isthe'/'. 
So we would then code It as follows: 

l/F 1/AHI 2/THV 3/ER 



A novel and useful new product has arrived for 
the Standard S50 Bus and Color Computer, the ALFORD 
and ASSOCIATES VS- 1 SPEAKER. This unit Is a voice 
synthesizer which will provide almost unlimited human 
speech capability. By the practice of phoneme coding, 
very Intelligent speech can be stored and recited back, 
by the computer, In short order and with a minimum 
amount of RAM or ROM overhead. The unit is Ideal for 
■canned messages' and other applications where a 
spoken only or In conjunction with a visual response Is 
desired. By 'fine tuning' the code, the speech can be 
made very 'human' like. 

The unit is a 30 pin wired and tested board that 
installs on the normal 30 pin I/O bus section, of the 
Standard SSO Bus computer or the side access slot of 
the Color Computer. It comes complete with a very 
comprehensive manual covering the art of synthesis 
methods for duplicating human speech, phonemes and 
what they are and how the human vocal tract forms 
these sounds, hardware Installation, software 
instructions for the speaker, oonf Iguratlon for the 
supplied VOX Editor, printer use with the editor (FLEX* 
- SSB" and others), VOX editor description and command 
descriptions, Iphone a telephone answering program 
(source), software utilization for various BASIC'S, a 
detailed hardware description of the unit, circuit 
drawing and board outlines, parts list and an appendix 
of many precoded words (makes learning a lot simpler). 

SYNTHESIS METHODS 

The documentation covers several methods of 
synthesizing the human voice. The first method Is by 
sampling an actual voice Input and storing It as a digital 
bit. This method probably produces the closest to 
actual human voice, but the disadvantages of complex 

26 „ 



Now the word takes on a question Inflection and 
would sound as 'Father?'. The spaces in the above code 
may be replaced by the comma. 

1/F.l/AHl, 2/THV, 3/ER 

Actually It is much simpler than the above would 
suggest. By using the table of words supplied it 
becomes Increasingly easier to code more complex 
words and sentences. This 'shorthand' type of coding 
allows words, with the proper Inflection, to be coded 
quickly. Also the editor allows the user to hear the 
word as soon as It Is coded. This sure makes things a lot 
nicer, during a phoneme coding session. 

SOFTWARE SUPPLIED 

The first software package supplied (make sure 
you specify the type disk system - FLEX - SSB) we will 
look at is the VOX EDITOR. This editor entails a 
comprehensive speech editing program. After 
configuring the editor to suit you system, terminal and 
printer, a one time function, you will be able to develop 
phoneme code in an orderly and simple manner. 



The commands arc 



E - Edit Function 
M - Move Functions 
S - Speech Functions 
D - Disk Functions 



When In one of the functions you will be 
'68" Micro Journal 



prompted for additional commands. Speech text 
commands Include (l)sert, (A)dd, (D)elete, (E)dlt, 
(N)umerlcs or (P)rlnt? 

The process Is a buffer editing process and you 
may Insert lines, words or characters at will, when 
satisfied you may save the buffer to disk or test It by 
having the editor send It out to your speaker (not 
. Included). The Insert command allows the Insertion of 
the edited word before the current word pointer In the 
buffer. The Add command adds the word to the end of 
the text you are editing. The Delete command deletes 
the current word. The Edit command allows editing of 
the pointed word In the buffer. Numerics display the 
hexldeclmal and decimal of the current word. This Is 
great for assembler and BASIC programmers. Print gives 
a hard copy of the entire text you are editing. 

MOVEMENT COMMANDS 



to complete the package Is a speaker or audio amplifier 
system (molex output connectors), the speaker or 
amplifier you furnish. In practice I found that the 
speaker Is all that Is needed as the onboard audio 
amplifier Is quite adequate to drive a 3 to 5 Inch 
standard 4-8 ohm speaker. If louder than normal sound 
Is needed then the amplifier system will have to be 
attached Instead of a speaker. 

Having experimented with this unit It will be 
Incorporated Into our commmunlty bulletin board as soon 
as we get It running. This will allow you to receive vocal 
instructions as well as digital instructions when you call 
In. It Is far superior to the other systems that we have 
evaluated. It should find many useful applications being 
developed for doing everything from listing out source 
and assembler programs to speaking 'BASIC as It Is 
running. As you come up with additional uses for this 
unit, please let me know. 



By keying 'M' you enter the MOVEMENT command 
portion of the program. The 'R' command returns you 
from this mode. The MOVEMENT commands are (F)oreward 
which moves the word pointer one word toward the end 
of the text file. (B)ackward does just the opposite. 
(S)tart moves the pointer to the beginning of the 
buffer. (E) moves the pointer to the end of the buffer.

SPEECH COMMANDS 

While In an editing session ft is sometimes 
desirable to have the computer speak the text for 
test purposes (or In my case JUST FOR FUN). The 
(S)peak command has the following sub-command 
functions. (T)hls speaks the word pointed to (current 
word). (l))p speaks everything from the start of the 
buffer up to and Including the current pointed word. 
(H)ere speaks from the current word to the end of the 
buffer. (A)ll speaks the entire buffer. (R)eturns to the 
main editor program. 

DISK COMMANDS 

The command (O)lsk calls the disk handling 
routines of the editor. THe (Slave command saves the 
entire buffer. (L)oad allows a previously saved text code 
file to be loaded. This command clears the buffer prior 
to execution. (A)ppend allows a saved file to be 
appended to the current buffer, without disturbing the 
current buffer or It's contents. Again (R)eturn gets us 
back to the main editing program. 

Included Is a telephone answering program that 
Is used at Alford Associates to answer their telephone. 
The code Is on the disk that comes with the SPEAKER 
board. It is an Interrupt driven program that works In 
foreground; It's operation Is transparent to the 
computer operator. This means that your phone can 
answer, wait for you to answer and give a message to 
the caller, all while you are still typing away on the 
keyboard. You will only detect a pause while the disk 
unloads the Iphone program (unless you vector the 
Interrupt to the program located In protected RAM) and 
then you may continue with normal DOS operations. Care 
should be exercised concerning other devices on the 
system that also generate Interrupts. 

in addition to the detailed hardware section of 
the manual there is a section concerning points on 
programming In machine, assembler or BASIC (could apply 
equally for practically any other language). 

The Introduction of the SPEAKER board by 
Alford and Associates (see advertising this Issue) brings 
to the Standard S50 Bus and Color Computer community 
a new and Innovative product. Fun for the hobbyist and a 
meanlngfu I tool to the business and more serious user. 

The board Is of excellent quality and comes 
wired and tested with sockets for all IC's. Dip switch 
selection makes things a lot simpler. All that Is needed

language programs that make up the most powerful 
business programming tool available for the 6809. It can be 
used by the relative novice, to implement an incredible 
variety of information storage and retrieval applications, 
without any programming. However, the programmer can 
use RMS as part o) the solution to a larger problem, saving 
many hours of unnecessary program development time. 
RMS can be used to handle data input, editing, validation, 
on-line retrieval, sorting and printed reports. Custom data 
manipulation can bo filled in by the user's BASIC programs.

SOFTWARE 
DEVELOPMENT 



The Micro Works Software Development 
System (SOS80C) is a complete 6809 
editor, assembler and monitor package 
contained In one Color Computer program 
pack! Vastly superior to RAM-based 
assemblers/editors, the SDS60C is non- 
volatile, meaning that it your application 
program bombs, it can't destroy your 
editor/assembler. Plus it leaves almost all 
of 16K or 32K RAM free for your program. 
Since all three programs, editor, assembler 
and monitor are co-resident, we eliminate 
tedious program loading when going back 
and forth from editing to assembly and 
debugging) 

The powerful screenorlenled Editor 
features finds, changes, moves, copys and 
much more. All keys have convenient auto 
repeat (typamatlc), and since no line 
numbers are required, the full width of the 
screen may be used to generate well com- 
mented code. 

The Assembler features all of the 
following: complete 6809 Instruction set; 
complete 6600 set suppoited for cross- 
assembly; conditional assembly; local 
labels; assembly to cassette tape or to 
memory; listing to screen or printer; and 
mnemonic error codes instead of numbers. 

The versatile A6UG monitor Is a compact 
version ol CBUG, tailored for debugging 
programs generated by the Assembler and 
Editor, it features examine/change of 
memory or registers, cassette load and 
save, breakpoints and more.

'TRADEMARK OF DIGITAL RESEARCH. 



WF ARE NOT ASSOCIATED WITH DIGITAL RE SI All! H OF CALIFORNIA THE SUPPLIERS OF CPM SOFTWARE 



SOFTWARE SYSTEMS AND SOL UTIONS FROM SD 

Software Dynamics has been offering quality software for 68xx class machines since 1977. We recognize that our 
customer's needs grow, and design our software to provide a growth path. SO offers compatible single-user, multi-user, 
and (soon) network systems to meet this need. Programs that run on the single-user system run unmodified on the multi- 
user and network systems. A virtual terminal driver assures that screen-oriented applications run on any CRT. 

The BASIC compiler is the result of 10 years experience in building BASIC interpreters and compilers. Sequential, random 
and indexed files are supported, along with true BCD numbers to eliminate conversion errors. Long variable names, blocks 
forstructured programming, and true multi- parameter subroutines and string functions aid prog ram construction and main- 
tenance. Compiled programs are both small and very fast, and the source is completely protected. 

SD also offers word processing and accounting software built to the same high standards as its system software.

64K BYTE CMOS STATIC 
RAM BOARD . . . with Battery Back-Up 

Using the latest in memory technology, the GIMIX 64K BYTE CMOS STATIC RAM BOARD 
combines the best features of previous memory boards on one board. 
FULLY STATIC MEMORY with its inherent low soft error rate and freedom Irom alpha-particle induc- 
ed errors. No complicated refresh timing or clocks required for data retention Fully compatible with 
any of the 6800/6809 DMA techniques. 

HIGH SPEEO 200ns. memorys for guaranteed operation at 2MH2 with no wait states or clock stret- 
ching required. 

ULTRA-LOW POWER CMOS RAM requires less than 1/4 AMP (250 Ma.) al8V fora fully populated 
64K BYTE board. Less power supply loading and heat generation for cool, efficient operation. 
N0N-V01 ATILE using an on-board nickel-cadmium battery. The board retains data even with system 
power removed With (he baltery fully charged, the contents of the memory remain intact (or a 
minimum of 21 days. 

HIGH DENSITY permits greater memory expansion to meet the needs of todays sophisticated, mutti- 
user/muiti-lasking operating systems. 

ADDRESSABLE in two 32K sections that have their own decoding for bolh the regular and extended 
(SS-SOC) address lines. Each section can be addressed to any 32K boundary in (he address range 
(1M BYTE with extended addressing) The 32K sections are divided into four 8K blocks that can be 
individually enabled or disabled Disabled sections do not occupy any address space 
RELIABLE like atl GIMIX products, the 64K BYTE CMOS STATIC RAM is designed with reliability in 
mind. Series damping resistors, a fully gridded power and ground layout, and generous power sup- 
ply decoupling, all contribute to reliability and data integrity. An unsafe voltage detect circuit inhibits 
writes to the board, when the 8V supply falls below a preset level, lo prevent loss of data during ihe 
transition between system and battery power. 

The GiMIX 64K BYTE STATIC RAM BOARD is ideally suited to a wide 

variety of applications. 

Its high density and ultra-low power consumption make it possible to greatly expand systems with a lew 
available bus slots and limited power supply capabilities 

The battery back-up feature is useful where data loss due to power failure cannot be tolerated, or as a replace- 
ment lor disk or tape storage where conditions such as environment prohibit their use Since the entire board 
can be hardware write protected by a switch located at the top of the board, it can also be used to emulate PROM 
or HOM memory This is especially useful during tirmware developement where frequent sottware changes must 
be made 

When the board is used in conjunction with a device such as the GIMIX MISSING CYCLE DETECTOR BOARD, 
which monitors the A.C. line and generates an interrupt when a power failure occurs, critical data can be stored 
and system integrity maintained during either expected or unexpected power outages 



The GIMIX 64K BYTE STATIC 
MEMORY BOARD is available in 56K 
and 64K versions Both version in- 
clude all ot the above teatures: gold 
bus connectors, and come tally 
assembled, burned in. and tested
